More and more scientists believe today that we do not have a soul, a mind of our own or a free will and they also claim that the idea of having a consciousness, is simply an illusion created by the brain itself. The idea - that everything that we regard as identity and a sense of the self - is a result of physical processes in the brain, flourishes and is nurtured within the neurosciences and computer sciences today.
The advances in some areas of the human brain sciences and the possible threats for the future became apparent to Ellen M. McGee and Gerald Q. Maguire already in 1999. They talked about ear- and eye implants but also about more advanced implants and sensors in the environment able to spy on the human being and to control behavior and the human mind. The same ethical questions arising then are still very important today.
